Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.

To be a good loser is to learn how to win.

Begin to be now what you will be hereafter.

It's always too early to quit.

What you do today can improve all your tomorrows.

The wise does at once what the fool does at last.

I can, therefore I am.

Things do not happen. Things are made to happen.
